Application filed March 21, 1908. Serial No. 422,443.

To all whom it may concern:

Be it known that LCLARKsoN P. HOCKET'I, acitizen of the United States, residing-at Kouts, in the county of Porter and State of Indiana, have invented certain new and useful Improvements, in Molds for Forming Walls or Buildings of Cement, Concrete, or

Analogous Materials, of which the followinventionarelates to molds for forming or buildings of cement, concrete or walls analogous materials; and it has for one of its ob ects to provide a simple and durable mold constructed with a view of forming in the face of a plastic wall lines simulating the spaces 'ordmarily present between the blocks of astone building. i I

Another object of the invention is the pro vision of a mold the major portion of which is formed of metallic sheets pressed into forms of the shapes necessary to give desired configurations to the part of a wall. L

Another object 1s the provision in a mold, of metallic forms 'in,combination with form holding bars in which'the forms are detachably secured, whereby when deemed expediurface of the larger ent some or all of the forms may be removed and replaced with forms of different character or of different sizes.

Another of the character stated of a frame comprising form-holding bars the ends of some of which are cut to fit the'sides of others, this in order that the direction of the lines simulating the lines between stones or bricks may be changed in the discretion of the builder.

Other objects and advantages of the invention will be fully unidrstood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which: I

and more particularly to Figs. 1 to-6,thereof: A A are the forms of my novel mold, which for the sake of cheapness-and lightness as Well as the facility with which they may be shaped are pressed or otherwise formed of sheet-metal. These impart to he face of'a and they are provided with flanges a dis Fig. 7 is a view showing in flat form a sheet-metal clamp which maybe Referring by letter to the said drawings fprms A' have i posed at approximate right gles to their major portions, the edges of which-flanges are bent rolled or otherwise enlarged as andicated'by'a, for a purose whi h will presently be pointed out. 1; this point I would have it understood that templates the rovision of a number of forms A'of di erent shapes and sizes, see Figs. land 6, for use interchangeably in the mold.

mold, which are preferably of metal. These bars B B each have one or two ooves 6 according to their location in e mold, which grooves 6 receive the edge-enlarge. ments or. of the forms A and also receive re movable form-retaining keys .0 designed,-as

their name im lies, to hold the forms in en-' gagement wit the bars B B and this 1-11 such manner that pressure within -the mold doesnot displace the keys and there is no liability of the keys being displaced when forms and hence are adapted to form =de-' pressions in the face of a plastic wall with a view of making the latter appear as'thongh the-line 4.4of Fig. 2,

built of stones, blocks or bricks. It will my invention con:

B B arethe forin-holding bars of the also be observed by reference to the drawings and particularly to Figs. 1 and 3, that the ends of the bars B are cut to fit the sides of the other bars B and consequently the direction of the lines in the surface simulating stones, blocks or bricks may be changed at will. The bars B and B are detachably connected together, the preferred mode being through the medium of studs f on the bars B disposed in sockets f in the bars B.

By preference the form-holding bars B are provided with comparatively broad outer edges and are hacked and crossed by frame bars E, of I-form, or other suitable shape in cross-section, which bars E are connected with the bars B through the medium of clamps which may be of any construction consonant with the purpose of my invention without involving departure from the scope of the same as claimed. The clamps F shown in Figs. 1 to 5 are similar in construction and therefore a detailed description of the one shown in Figs. 3 and 5 will sutlice to impart a definite understanding of all. The said clamp F, Figs. 3 and 5, comprises a bar portion Z having a hook-shaped enlargement e to engage one side of its comlernentary bar B, and a hook-shaped memer f pivoted at g on the bar portion d and arranged in the position shown to hold the bar B and when swung to a position at right angles to that illustrated, to release the said bar B. As shown in Figs. 2, 4 and 5, the bars B are provided with lugs f in which the bars E are arranged and supported. It will be observed that these clamps maintain the keys C against lateral displacement.

In lieu of the clamps F, sheet-metal clamps F one of which is shown in flat form in Fig. 7, may be employed, in which case the lugs f on the bars B will be dispensed with. The said clamp F comprises a body m adapted to be interposed between a bar B and a bar E and having cars a and p adapted when bent to receive opposite edges of the flange on bar E and also having ears 1 and s adapted when bent in the opposite direction, with reference to the cars a and 77, to receive one edge of the flange on bar B, and a swinging member 2, pivoted at u to the body m and having an ear 1: adapted when bent to receive the opposite edge of the flange on bar B and retain said bar in engagen'ient with the ears '2". and s. The said swinging member If is swung in the 'rcction indicated by arrow into engage ...=ient with the bar B and is equipped with an ear to and a tongue a; the said car in being designed to be bent around the edge on of the body at to resist the pressure 9f bar B against ear 1:, and the tongue a; being ar ranged to engage one of the series of stops 3/ on body m with a view of preventing casual movement of the member t in the direction and being disposed in opposite to that indicated by the arrow. It will be noticed, however, that when the tongue 02 is pried out of engagement with a stop 3 the member t may be readily swung outward-i. 0., inthe direction opposite to that indicated bythe arrow. It will be observed in this connection that the cars a and 32 not being opposite the flange on bar E are easily caught when the body at is turned to a position bar; also, that when clamps such as F are employed smooth and straight bars B and E may be employed, and the points of in tersection thereof may be readily changed at will. I

It will be gathered from the foregoing that my novel mold is adapted to be used with great facility in the production of walls or buildings of plastic material; also, that the mold is simple and strong in construction and is not unduly heavy, and that when occasion demands some of the forms A may be readily removed and as readily replaced with larger or smaller forms or forms corresponding in size but different in shape or configuration.

As before stated the construction herein shown and described constitutes the best practical embodiment of my invention of which I am cognizant, but I would have it understood that in the future practice of the invention such changes may be made in the form, construction. and relative arrangement of the parts as fairly fall within the scope of my invention as defined in the claims appended.
